Buzzer Project #1 - On and Off

Buzzer Project #2 - Simple Music and Tones

In this activity you will see how to use the tone functions to program simple sounds and songs. This activity will highlight the following code; tone(pin, frequency, duration)pin = the # of the pinfrequency = the frequency, pitch or note duration = how long the note lasts

After you get it to work, change some of the parameters like the delay time.

Buzzer Project #3 - La Cucaracha (creating a tone library)

Buzzer Project #4 - Shave and A Haircut Variation

In this project you will experiment with the Arduino IDE. You learn how to play a melody by including an array that declares the notes. Here you will need to include the musical notes as part of the program.

Buzzer Project #5 - Photo Resistor (Theramin)

Buzzer Project #6 - Piezo with Potentiometer

Buzzer Project #7 - Play Melody with Button

Download the File Below and open to copy and paste the code for your Sketch more easily.

Buzzer Project #8 - Button Piano

Follow the wiring sketch to wire the device correctly. Then start the Arduino IDE (app) and then type in the code as shown. Once done, try to play Mary had a little lamb. Be sure to check all the wiring. Use the small buttons in your kit. Although the code is written for 9 buttons and sounds, you will only use 5 buttons.

Piezo buzzer is an electronic device commonly used to produce sound. Piezo buzzer is based on the inverse principle of piezo electricity discovered in 1880 by Jacques and Pierre Curie. It is the phenomena of generating electricity when mechanical pressure is applied to certain materials and the vice versa is also true. Such materials are called piezo electric materials. Piezoceramic is class of manmade material, which poses piezo electric effect and is widely used to make a disc, the heart of piezo buzzer. When subjected to an alternating electric field they stretch or compress (vibration), in accordance with the frequency of the signal thereby producing sound.

Photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity.
